which chip should capsule endoscope use? What is the actual maximum speed?

[Kenneth]

For new development check out the nRF52832 (or other devices in the nRF52-family):
https://infocenter.nordicsemi.com/topic/struct_nrf52/struct/nrf52832.html?cp=3_2 

The SDK documentation can be found here:
https://infocenter.nordicsemi.com/topic/struct_sdk/struct/sdk_nrf5_latest.html?cp=5_1 

The throughput depends on the configuration of the BLE link, but some numbers are found here (see Table 2 at the bottom):

Thank you very much. For power consumption and throughput, Is nRF52832  bettor than nRF24LE1?

[zhaokun_01]

think you very much

What is the maximum throughput of nRF24LE1?With the nRF52 DK single board, the maximum throughput is 1Mbps, which does not reach 1376.2 kbps. why?

I don't recommend to use the nRF24LE1 for any new development. You can find throughput numbers for the nRF52 running BLE here:

I just did what you gave this specification. the specification is https://infocenter.nordicsemi.com/topic/sds_s132/SDS/s1xx/ble_data_throughput/ble_data_throughput.html?cp=4_5_2_0_16  . which does not reach 1327.5 kbps, Configuration is as follows:

Protocol	ATT MTU size	LL payload size1	Connection interval	Method	Maximum data throughput (LE 1M PHY)	Maximum data throughput (LE 2M PHY)
GATT Server	247	251	50 ms	Send Notification	702.8 kbps	1327.5 kbps
				Receive Write command	702.8 kbps	1327.5 kbps

nRF24LE1 is used in old products. The current throughput rate is 500kbps. I want to increase the throughput rate, but I don't know how to do it.
